Abstract

This apparatus comprises a plurality of fluid jet amplifier devices 1, 2 and 3. The maximum number of different signals possible is double the number of such devices used. In each device, a stream of power fluid which is supplied via a respective inlet 4 is divertable into a corresponding outlet 5 or 6 according to whether a control pressure fluid is supplied to a control port 7 or 8, respectively.

Generating Timed Pneumatic Pulses

This apparatus comprises a plurality of fluid jet amplifier devices 1, 2 and 3. The maximum number of different signals possible is double the number of such devices used. In each device, a stream of power fluid which is supplied via a respective inlet 4 is divertable into a corresponding outlet 5 or 6 according to whether a control pressure fluid is supplied to a control port 7 or 8, respectively.

Assume that a pressure fluid pulse is supplied to a reset port R via a valve V from pump P and that valve V is then closed to cut off port R from the pump and from atmosphere. In such case, the fluid power stream in device 1 is diverted into its outlet 5. This stream then flows via a timing volume A to control port 8 of device 2 to shift its stream into the corresponding outlet 6. The stream in device 2 then flows via timing volume B to control port 7 of device 3. Thereafter, the power stream in device 3 is shifted to outlet 5 and flows via timing volume C to control port 8 of device 1 to shift the power stream in device 1 to outlet 6. The power stream in device 1 now flows via timing volume D, and causes the streams in devices 2 and 3 to be diverted successively into timing volumes E and F. From timing volume F fluid feeds back to control port 7 to shift the power stream in device 1 to volume A and thus initiate a repetition of the complete clocking cycle just described.

Pneumatic pulses are generated indefinitely as long as valve V r...
